HI every one today i am going to explain you ho you can hack remote pc using social engineering tool kit present in backtrack.
so lets do it mostly i will show you rather than putting lots theory stuff. and this is the quick way to learn it and don't forget to practice so follow these step by step.

Now after opening social engineering tool kit press 1.

Next select option 2

Next select option 1

After that select 2 and select nat/port forwarding to be no and give your ip address .you can easily know your ip address by
typing ifconfig command and then provide a url which the victim will be redirected after clicking link.just below see image.

Next come the important stuff select the pay laod to be 14 that is shellcodexec AV Safe. and for port to listen just press enter as it take 443 to be default port.and in the end select the payload to be deliver by shellcodeexec to be 1 that is Windows meterpreter reverse tcp.
